Step-by-step explanation:
Let's solve 
Divide both sides by 100:

Take the square root of both sides:
(I did not keep the negative value because it doesn't matter since we are only considering even powers of
.)
So now let's plug it into:



To find the volume of a container, you simply multiply: L(ength) x B(ase) x H(eight).
In total, you should get a volume of 1078in^3 (the bigger container) plus 175in^3 (the smaller container on top of the bigger one). The answer is 1,253in^3.
